Fireworks not working

After I installed this my players cannot set off fireworks. I'm trying to find the right wording but nothing is working

Add an entity group that includes the fireworks

{
"name": "fireworks",
"members": "PFXRepeatingFirework, BaseFirework, MortarFirework",
"exclusions": ""
},

Then a rule such as "players can hurt fireworks",

 

Someone write that for another player, its worked on me
